Castle Upgrades

Main Article: Castle
To be placed on an island, each monster requires a specific number of beds. For Natural Monsters, this is equal to the number of elements that monster represents. Ethereal, Supernatural, Seasonal, and Rare (only the Rare Wubbox) Monsters each have varied bed requirements. Upgrade the Castle to unlock more beds.

Strategy

While the song of the island is crucial, users may also want to use some of these numbers to help with planning which monsters to feed first and make 100% happy first, as well as plan frequency of coin collection. The numbers below are as follows:

Rate

Rate of income per bed at level 15 and at 100% happy

Max

Maximum income per bed at level 15

Time

Time to maximum income at level 15 and at 100% happy

(shown as Hours : Minutes : Seconds)

It should be noted that Rate is half for 0% happy, and Time is doubled for 0% happy.
